[Retracted] Kukoamine A Improves Mycoplasma pneumoniae Pneumonia by Regulating miR-222-3p/Superoxide Dismutase 2

Figure 1

Serum exosomes of MPP patients induce inflammation in human alveolar basal epithelial cells A549. MPP serum exosomes (100 μg/mL) were treated with A549 cells, followed by 24 h of treatment with KuA at different concentrations (0, 5, 10, and 20 μM) as indicated. (a, b) ELISA assay for assessment expression of IL-6 (a) and TNF-α (b) in the cell supernatant. (c, d) RT-qPCR was used for assaying the mRNA expression levels of SOD2 (c) and NF-κB (d) (3 repeats in each treatment group). vs. control (A549 cells without treatment); ^#, ^##, ^### vs. ; ⁺ vs. ; ^& vs. .
